AIR-PRESSURE CORK.

To all whom it may concern:

Be it known that WEQ'JOSEPH S. LEISURE and PERL J. ROBINSON, citizens of the United States, residing at Ingleside, in the county of Adams and State of Nebraska, have invented certain new and useful Improvements in Air-Pressure Corks, of which the following is a specification.

This invention relates to corks for hottles, the object of said invention being to provide a cork which will fit bottles and jugs, the neck portions of which vary in diameter, said cork being so constructed as to eject the contents of the bottle without handling the same.

With these and other objects in view, the present invention consists in the combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claim, it being understood that the changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings: Figure 1 is a view showing the cork arranged within a bottle, Fig. 2 a section on the line 3--3 of Fig. 3, and, Fig. 3 a sectional view taken on the line 22 of Fig. 2.

In the drawings: 10 designates a stopper which is formed of hard rubber, the periphery 11 being of soft rubber, in order that said stopper may accommodate itself to vessels whose mouth portions vary in diameter. A passage 12 extends entirely through the stopper, hollow projections 12' and 12 being arranged on the stopper of the ends of said passage. A curved spout 13 is secured to the projection 12, and a tube 14 is secured to the projection 12", said tube extending within the bottle. A secondpassageway 15 extends through the stopper, the hollow projection 15 being arranged at one end of the same. To the projection 15 is secured the tube 16 which isconnected to an air compresser 17, which, when operated forces air into the receptacle in which the cork is positioned. A passage.- way 18 is arranged centrally within the stopper, said passageway extending entirely through the same, and terminating in the flared portion 19, which is made conical to accommodate the valve plug 20. The plug 20 is arranged upon a stem 21, which extends through the passageway 18, its end Specification of Letters Patent. Patented Nov, 28, 1911,

portion extending beyond the end portion of the stopper. The passageway 18 is provlded with the enlarged portion 22 in which rests a sleeve 23, provided with a screwthreaded portion 24. A second sleeve 25 is adapted to screw into the sleeve 23, the member 21 passing through both sleeves. Secured to the member 21 is a spring 26 which bears against the base portion of the sleeve 23, the normal tendency of said spring being to hold the plug 20 in contact with the conical opening 19, thereby closing the passageway. It will be seen, however, that when the end portion 27 of the member 21 is forced downwardly against the tension of the spring 26, the plug 20 will be released from contact with the end portion of the channel.

It will be seen that when air is compressed by means of the bulb 17, the same will enter the receptacle and force the liquid contained therein, through the tube 14:. It will thus be seen that the contents of the bottle may be removed without the hand of the operator coming in contact with the bottle, there being no necessity for tilting the same, or in any way removing it from its normal position.

In filling smaller vessels from the receptacle to which the device is attached, it is necessary to instantaneously cut off the supply when the smaller vessel has been filled. This is accomplished by relieving the airpressure in the receptacle. When the smaller receptacle has been filled, the end portion 27 of the member 21 is depressed against the tension of the spring 26, thereby forcing the plug 20 from the mouth of the channel 18, and allowing the air, which is under pressure within the receptacle, to escape through the opening 28 formed in the sleeve 25. It will be seen that as soon as the pressure within the receptacle is relieved, the supply of fiuid will be immediately cut off.

A device of this character is particularly adapted for emptying heavy and cumbersome vessels without the necessity of handling the same. As before stated, the cork is provided with an exterior portion 11 of flexible material, said material being so soft and pliable as to permit the device to be inserted within receptacles, the neck portions of which differ greatly in diameter.

A device constructed as hereinbefore described, will not only be very eflicient in practice but the structure is such that said device can be manufacured at a very small cost and the parts readily assembled.

What is claimed is:

As an article of manufacture, a plug stopper, a resilient sleeve on said stopper, having a plurality of passages extending longitudinally therethrough, said stopper being formed with a central longitudinally arranged passage, a valve seat formed at the lower end of said central passage, said central passage terminating at its upper end in an enlarged circular recess, a pair of telescoping cylindrical members seated within said recess, the outer end of each cylindrical member having a Wall provided with central openings, a rod extending vertically throughsaid openings and said central passage, a valve head on one end of said rod, one of said cylindrical members being secured to said rod at its upper end, a coil spring Within said cylindrical members and encircling said rod, and a button on the upper end of said rod for depressing said rod to move said valve head.

In testimony whereof We aflix our signatures, in presence of two Witnesses.
